    “…METHODS: QTP was conjugated with different chain length fatty acids (C10–decanoic acid, C14–myristic acid, C18–stearic acid) to obtain QTP-fatty acid conjugates (QFCs: QD, QM, QS) by exploiting 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/4-dimethylaminopyridine (EDC/DMAP) conjugation chemistry. Then, the solubility, partitioning coefficient (log P), cell viability and cleavage kinetics of QFCs were evaluated. …”

    “…BACKGROUND: In 2003, residents of the District of Columbia (DC) experienced an abrupt rise in lead levels in drinking water, which followed a change in water-disinfection treatment in 2001 and which was attributed to consequent changes in water chemistry and corrosivity. OBJECTIVES: To evaluate the public health implications of the exceedance, the DC Department of Health expanded the scope of its monitoring programs for blood lead levels in children. …”

    “…Proteolipide C was inactive. Correlation of the chemistry of fractions with their antigenic activity suggested two possibilities: (a) that there might be two antigens, one proteolipide and the other non-proteolipide; or (b) that a small specific proteolipide is responsible for all the observed activity. …”
